Abstract
An in-home method for treating a fabric article in need of treatment and a new to the world, in-home, self-contained, stand alone fabric article treating apparatus, such as a “cabinet”-type of apparatus, useful in such method is provided.
Claims1
An in-home method for treating a fabric article in need of treatment comprising:
- a. providing a new to the world, in-home, self-contained, stand alone fabric article treating apparatus designed for domestic use, wherein the apparatus comprises 1) a housing which defines a fabric article receiving volume, 2) a fabric article fixturing system which immobilizes and tensions the fabric article, and 3) a source of an electrically charged liquid comprising water and a member selected from the group consisting of organic solvents, surfactants, wrinkle releasing agents, anti-static agents, soil release agents, colorants, brighteners, perfume and mixtures thereof, said liquid having an applied potential of from about 0.2 kV to about 50 kV:
- 4) a vent;
- and optionally, 5) a safety system capable of preventing contact of the electrically charged liquid to a user of the fabric article treating apparatus;
- b. positioning the fabric article in need of treatment, said article comprising malodors, within the fabric article receiving volume by associating the fabric article with the fabric article fixturing system under tension to mechanically stretch the article;
- c. operating the fabric article treating apparatus such that the source of the electrically charged liquid delivers the electrically charged liquid to the fabric article positioned within the fabric article receiving volume and drives deposition of the liquid onto the fabric article, such that the fabric article is cleaned, dewrinkled and/or deodorized by said treatment, wherein the electrically charged liquid being delivered to the fabric article is formed into droplets by electrostatic ligament atomization;
- and wherein
- d. steam is supplied to the article to remove said malodors therefrom by passage of said malodors out through said vent prior to the delivery of the electrically charged liquid in step (c);
- and
- e. drying the treated fabric article with warm air after application of the electrically charged liquid to the article, wherein the air used during the drying is at a temperature from about 50° C. to about 100° C.;
- and
- f. wherein said electrically charged liquid further comprises cyclodextrin and a fabric shrinkage reducing composition comprising neopentyl glycol.
